Pultruded Fiberglass Grating (similar in form to metal bar grating) is stronger, lighter, equally corrosion resistant, and in most cases, more economical than Molded grating. Additionally, pultruded grating can be larger than molded panels and can be fabricated to custom sizes. In most applications, pultruded fiberglass grating will represent the best product at the lowest price.

Pultruded Fiberglass Grating is manufactured by assembling two structural fiberglass shapes (the cross and bearing bars) into a grid pattern. These bar shapes are made by "pultrusion" - a continuous molding process utilizing glass or fibrous reinforcement in a polyester or vinyl ester resin matrix. Selected reinforcement materials like glass strands, mat or cloth thoroughly impregnated with the liquid resin. The laminate is formed in a geometric shape (either a "T" or an "I") and pulled through a heated steel die. Finally it solidifies into the exact shape of the die cavity after being continuously pulled by the pultrusion machine.

  • Strength: Pultruded Grating products offer superior strength and stiffness. This allows the highest strength to weight ratios of all grating systems.
  • Corrosion Resistance: Pultruded Grating is superior to stainless steel, aluminum and galvanized gratings. It can be used in extreme environments.
  • Fabrication Features: Many panel sizes allow for versatility and longer spans to reduce waste.
  • Safety Surface: The walking surface of most Pultruded Grating may have a coarse epoxy grit bonded to both the bearing and cross bars for surer footing.
